Optical filters still hold a firm place in photography and videography, even if many believe that all effects can be digitally edited in post-production. But why are they so important, and what makes magnetic round filters so special?
Why optical filters are still indispensable
Digital post-processing is undoubtedly a powerful tool, but it quickly reaches its limits when faced with certain challenges. An example of this is avoiding overexposure or extreme light reflections. Optical filters intervene in the image capture process itself, altering the incoming light before it reaches the sensor. This leads to results that are often impossible or very difficult to replicate in post-processing. Here are some examples:
- ND filters (Neutral Density Filters) reduce the amount of light reaching the sensor, allowing for longer exposure times or wider apertures. This results in soft water surfaces or dynamic motion blur with brilliant exposure.
- CPL filters (Polarizing Filters) remove distracting reflections on surfaces like water or glass and ensure richer colors. Digital post-processing could at best simulate this, but it cannot physically alter the light conditions afterwards.
- GND filters (Graduated Neutral Density Filters) reduce light transmission in specific areas of the image, usually the sky. This allows photographers to achieve balanced exposure between bright and dark image areas without losing important details. They are particularly useful in landscape photography to create dramatic skies and evenly exposed foregrounds.
- UV filters (Ultraviolet Filters) block ultraviolet rays, which could otherwise lead to blur or a blue cast in your images, especially when shooting at high altitudes or on the coast. Additionally, they provide physical protection for the lens without affecting image quality, which is why they are often used as standard lens protectors.
The advantages of round filters
Round filters offer several crucial advantages over other filter types, such as rectangular filters – without devaluing other options. They are quick to mount, fit perfectly on the lens, and offer excellent portability. For photographers who are often on the go or work in spontaneous situations, round filters are ideal. They take up little space and are quicker to change, which is particularly beneficial when light conditions change rapidly.
Furthermore, round filters protect the lens and remain securely mounted – without an additional holder or clamping mechanism.
The F:X Pro Magnetic ND Filter Set Mark II: Flexibility and Performance in Focus
With the set consisting of a CPL filter and ND8, ND64, and ND1000 filters, you are equipped for almost any photographic situation. Whether you want to achieve dramatic long exposures in landscape photography or clear reflection reductions in architectural photos – this set offers maximum flexibility.
A particularly useful feature is the magnetic changing mechanism: instead of laboriously screwing on filters, you can simply swap them magnetically. Only the base ring is screwed onto the lens once. This saves valuable time and ensures that you don't miss a shot due to a lengthy filter change. Additionally, the improved frame makes it easier to separate the filters from each other, and thanks to the printed name on the filter edge, you can always quickly grab the right filter.
Why a variable ND set is practical
A variable ND set allows photographers and videographers to seamlessly adjust exposure – from ND2 to ND500 – thus avoiding constantly switching between different filters. Especially in changing lighting conditions, which often occur during outdoor shoots, a variable ND filter enables quick adjustments without interrupting the shot. This saves valuable time and provides more flexibility, as you can react to various scenarios with just one ND filter.
The F:X Pro Magnetic Mark II VND Set utilizes these advantages with a magnetic holder for lightning-fast filter changes. The set consists of three ND filter elements, which allow precise exposure adjustment over nine stops, ensuring maximum control in all lighting conditions.
One set for all lenses: The role of step-up rings
A particular strength of magnetic round filters is their compatibility with different lens diameters. With the F:X Pro Magnetic Step-Up Ring Mark II, you can use filters with an 82 mm diameter on lenses with smaller diameters. This means you don't need to buy multiple filter sets for different lens sizes. One set, flexibly adaptable with step-up rings, covers all your lenses. This keeps your equipment light and organized.
For which subjects are the filters ideal?
- CPL filter: Ideal for scenes where reflections play a role, such as glass facades or water surfaces. Colors are also intensified, and the sky appears a deeper blue – perfect for landscape or architectural photography.
- ND8: On slightly cloudy or overcast days, this filter can be used to subtly represent movement in clouds or water, while still preserving enough light for detail.
- ND64: This filter allows for longer exposures in daylight – ideal for waterfalls or flowing water to create a silky texture.
- ND1000: A must for dramatic long exposures in bright light, for example, for soft cloud movements or crowds of people disappearing in motion.
Safe storage and transport
Thanks to the included magnetic caps, the magnetic round filters can be safely stacked and transported. Alternatively, our 4-piece Round Filter Bag offers optimal protection. The padded bag has four compartments for filters up to 95 mm in diameter, as well as an additional compartment for accessories such as cleaning cloths. With a practical eyelet and a carabiner, it can be conveniently attached to a backpack or tripod, so your filters are always at hand.
Cleaning and care
Regular cleaning is important for the longevity of your filters. We recommend the Cleaning Set Universal V2, which is equipped with a blower, cleaning brush, and microfiber cloth for all eventualities. For on-the-go, the Magic Cleaning Cloth quickly and efficiently removes dust and fingerprints from your filters. These simple measures ensure that you can always take sharp images without streaks or scratches.
Conclusion: Perfect filters for demanding photographers
The F:X Pro Magnetic ND Filter Set Mark II is an excellent tool for photographers and videographers who value flexibility, quality, and speed. It is a set that supports you in every situation and is so uncomplicated that you can fully concentrate on photography. With the magnetic system and step-up rings, you save time and space – all while achieving maximum image quality.
